BOTTLE-WASHING BRUSH.

Specification of Letters Patent.

4Patented May 2o, ieiv.

Application filed February 8, -191'?. Serial No. 147,469.

i brush for washing the insides of bottles, the

same being particularly adapted to wash and clean the insides of carboys.

The invention consists in a brush constructed as hereinafter set forth in the specication and particularly as pointed out in the claims.

Referring to the drawings, Figure l is a sectional elevation of my improved brush, a carboy being shown in connection therewith and broken away.

Fig. 2 is a sectional elevation similar to Fig. 1 illustratingthe brush advancedv into the carboy and contacting with the bottom thereof. 1

Fig. 3 is a detail section taken on line 3-3 of Fig. 1.

Fig. 4 is a detail section taken on line 4--4 of Fig. 1. V

Fig. 5 is a perspective view of the wiper tube. 1

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 6 is a rubber tube slitted longitudinally thereof at 7 for a portion of its length to form a plurality of Vwipers 8. 9 is a holder having a passage 10 extending therethrough and a recess 11 in its front end containing the unslitted portion of the rubber tube 6. 12 are scrubbers, each consisting of a rubber pad 13 which is fastened to a spring metal shank 14, said Shanks bel especially the bottom inner surface thereof.

ing clamped to the holder 9 by means of a clamp sleevel lrwhich has a conical bore and is forced upon a conical portion 16 of the holder 9 by a pipe 17 which has screwthreaded engagement with the holder 9. The holder 9 is also, provided in its periphery with oppositely disposed grooves 18 in which the shanks 14 lie (see Fig. 3). v

The metal Shanks 14 project between two adjacent wipers 8 andare inclined toward the median axial line of the'holder 9 at the forward end thereof, thus holding the tube 6 in the recess 11. A sleeve 19 encircles the 5D wipers 8 and the pads 13 when the brush is drawn into said sleeve as illustrated in Fig. 1 and said sleeve is rotatably mounted in a bearing 20. A bell-inouthed nozzle 21 is fastened to rsaidbearing at its front end adjacent to the i sleeve 19 and is adapted to guide the wipers and the scru'bbers into said sleeve when theV brush is withdrawn -from the bottle. The bell-mouthed nozzle 21 also serves as a rest ,agnd centering device for the bottle or car- Oy. j

lie pipe 17 isvrotated by means of any suitable mechanism and the water for washthrough the passage 10 in the holder 9 and through the bore of the tube G into the bottle 22.

The general operation of the device hereinbefore specifically described is as follows: Assuming the parts to be in the relative positions illustrated inFig. 1, with the neck of the bottle resting against the interior of the bell-mounted nozzle 21,.the holder and brush, together with the-.pipe 17, are moved toward the left, 'Fig..1,.until they enter the bottle 22. The water at this time is passing -into the bottle through the pipe 17, holder l9. and tube 6. A rapidrotary motion is imparted to the pipe 17 which communicates a rotary motion to the holder 9 and to the brush and also to the sleeve`19.

In Fig. 2 the brush is shown as advanced into the bottle in dotted lines, with the wipers extending outwardly to contact with the inner surface of the bottle, due to centrifugal force, and in full lines said wipers are shown as contacting with the bottom 23 of the bottle. rIhe pads 13 serve to scrub the inside of the bottle and a portion of the bottom thereof and also the corners 24 as seen in Fig. 2, while the wipers also assist in cleaning the interior of the bottle and Vhen the bottle is thoroughly washed, the

brush is moved toward the right, Figs. 1 and 2, and 'is drawn into the sleeve 19 which continues rotating so long as the'brush-is rotated by the pipe 17, thus preventing injury to the wipers and to the scrubbers.

Having thus described my invention, what I claim and desire by Letters Patent to secure .isr

1. A bottle washing brush having, in combination, a rubber tube slitted longitudinally thereof for a portion of its length to form a plurality of wipers, a holder for said tube having a passage extending longiing the bottles passes through said pipe and tudinally therethrough with a. recess in one end thereof containing the unslitted portion of said tube, and a scrubber consisting of a rubber pad and a spring metal shank, said shank being fastened to the periphery of saidY holder.

2. A bottle washing brush having, in combination, rubber tube slitted longitudinally thereof for a portion of its length to form a plurality of wipers, a holder for said tube having a passage extending longitudinally therethrough with a recess in one end thereof containing the unslitted portion of said tube, and a scrubber consisting of a rubber pad and a spring metal shank, said shank being fastened to the periphery of said holder and projecting therebeyond and between two of said wipers.

3. A bottle washing brush having, in combination, a rubber tube slitted longitudinally thereof for a portion of its length to forni a plurality of wipers, a holder for said tube having longitudinal grooves in its periphery and a passage extending longitudinally theretl'irough with a recess in one end thereof containing the unslitted portion of said tube, a scrubber consisting of a rubber pad and a spring metal shank, said holder having a conical portion, Va sleeve with a conical bore having engagement with the conical portion of said holder and a pipe having screw -threaded engagementV with said holder and bearing against one end of said sleeve whereby said metal shanks may be clamped to said holder Within the longitudinal grooves provided in the periphery of said holder.

Copies of this patent may be obtained for five cents each, by addressing the "Commissioner of Patents 4L. A bottle washing brush having, in combination, a rubber tube slitted longitudinally thereof for a portion of its length to form a, plurality of wipers, a holder for said tube having a passage extending longitudinally therethrough with a recess in one end thereof containing the unslitted portion of said tube, a scrubber' consisting of a rubber pad and a spring metal shank, said shank being fastened to the periphery of said holder, a rotary sleeve adapted to. encircle said wipers and scrubber and a bearing within which said rotary sleeve is mounted.

5. A bottle washing brush having, in combination, a rubber tube slitted longitudinally thereof for a portion of its length to forni a plurality of wipers, a holder for said tube having a passage extending longitudinally therethrough with a recess in one end thereof containing the unslitted portion of said tube, a scrubber consisting of a rubber pad and a spring metal shank, said shank being fastened to the periphery of said holder, a. rotary sleeve adapted to encircle said wipers and scrubber, a bearing within which said rotary sleeve is mounted and a bell-mouthed nozzle fast to said bearing adjacent to said rotary sleeve and adapted to guide said wipers and scrubber thereinto.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
